Working principle
The main contact of the molded case circuit breaker is manual manipulation or electric closing. After the main contact is closed, the free release mechanism locks the main contact into the closing position. The over current trip coil and the thermal trip element are connected in series with the main circuit. The under voltage release coil and the power supply are connected in parallel.
